The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re
...
placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The Africa Centres for Disease Control and Prevention (Africa CDC) Biosafety and Biosecurity Initiative was launched by the Africa CDC in April 2019 with the aim of strengthening the African Union (AU) Member States’ biosafety and biosecurity systems and enabling them to comply with national and i
...
nternational requirements for biosafety and biosecurity including the International Health Regulations (IHR) (2005), the Biological Weapons Convention (BWC), and United Nations Security Council Resolution (UNSCR) 1540 and the multi-country Global Health Security Agenda (GHSA). The World Health Organization (WHO) Joint External Evaluation (JEE) and the Global Health Security Index report confirmed the known capacity gaps in biosafety and biosecurity among Africa Union Member (AU).
The regional consultations by Africa CDC conducted between 2019-2021 highlighted the deficiency or limited availability of standardized and regionally recognized training programs in the continent, limiting biosafety and biosecurity capacity building efforts in the region. In response, Africa CDC working with AU Member States developed a home grown, implementable and accessible professional training and certification program that is both recognized and endorsed by AU Member States. The Regional Training and Certification Program for Biosafety and Biosecurity Professionals, for African Biosafety and Biosecurity Professionals (RTCP-BBP) has four (4) areas of specialization, namely
Selection, Installation, Maintenance and Certification of Biological Safety Cabinets
Biorisk Management
Design and Maintenance of Facilities Handling High Risk Pathogens (Biocontainment Engineering)
Biological Waste management

Diabetes mellitus is a major cause of morbidity and mortality in Scotland and worldwide, with an increasing prevalence. In 2009 there were around 228,000 people registered as having diabetes in Scotland, an increase of 3.6% from the preceding year. This increase relates, in part, to the increasing a

The objectives of this guideline are the same as those of the 2011 edition, namely to provide evidence-based normative guidance on interventions to improve adolescent morbidity and mortality by reducing the chances of early pregnancy and its resulting poor health outcomes. The specific objectives of
...
the guideline were to: 1. identify effective interventions to prevent early pregnancy by influencing factors such as early marriage, coerced sex, unsafe abortion, access to contraceptives and access to maternal health services by adolescents; and 2. provide an analytical framework for policy-makers and programme managers to use when selecting evidence-based interventions to prevent early pregnancy and negative health outcomes when they occur that are most appropriate for the needs of their countries and context. The recommendations and best practice statements described in this document aim to enable evidence-based decision-making with respect to preventing early pregnancy and poor reproductive outcomes among adolescents in low- and middle-income country contexts.

This comprehensive reference document is intended for those responsible for training in SMC (Seasonal Malaria Chemoprevention). It assumes that SMC will be implemented using the Community Health Worker strategy.
Community led-monitoring is based on the principle that «Nothing that is done for us should
be done without us”. The combination of this principle with evidence shows that community-led
monitoring is an important driver of improved service delivery and health outcomes that needs to

sized. Thus, the community must participate at all stages of the fight against malaria.
This guide will be useful to CSOs working in the field of malaria in the conduct of community-led
monitoring of activities efficiently and allow these CSOs to know their role and responsibilities in this
exercise at each key stage. This guide will also provide CSOs and communities affected by malaria
with templates of monitoring tools adapted to key malaria programs.

s dedication to utilising digital technologies and AI to enhance healthcare delivery, facilitate data-driven decision-making, and bolster the resilience of the healthcare system. Although AI integration in Tanzania’s health sector is still in its infancy, a growing number of initiatives are highlighting its potential in clinical care, research, and system management. The Ministry of Health, in collaboration with partners including the President’s Office (PORALG), Fondation Botnar, MUHAS, UDOM and PATH, has spearheaded this initiative with the aim of using AI to minimise errors, improve clinical outcomes and boost the efficiency of the health system.

ctious diseases often spread across borders due to population movement, trade, and migration, while surveillance systems and data-sharing mechanisms frequently remain nationally focused and fragmented.
The framework proposes strengthening regional coordination, harmonizing surveillance systems, enhancing information sharing between countries, and building laboratory and workforce capacity. It also emphasizes timely detection of cross-border health threats, joint outbreak investigations, and improved communication among Member States. Overall, the document aims to enhance preparedness, early warning systems, and collective response to public health threats across the African continent.
